DO NOT USE THIS
We thought that we were helping our dog, he seemed so frustrated with the fleas. So we did what we thought best to do. we bought Hartz 2 in 1 flea and tick dog spray, and used as directed and 3 of our dogs that were constanly scrathing with fleas. Not knowing all the other Helpless animals that have been kill from this horrible product. About two days later my mom started to read about all the victums of Hartz, and instantly began to give them all baths. and now this morning i wake up to one of my dogs fast asleep never to awake again. im sorry if this is hard to understand. i am too upset to type and i am furious that this is a known problem with this company and it remains on the shelf.
